Abstract (en)
[origin: WO2015082814A1] The invention relates: ● to a glazing unit including a hydrophilic layer comprising a polyurethane matrix incorporating bis-urea functions; ● to a process for manufacturing this glazing unit, in which a) a solution containing at least one isocyanate, a polyol and a bis-urea having a polyol function, polyvinylpyrrolidone, a film-forming agent and a solvent, is deposited on a glazing substrate; b) the glazing unit, containing the substrate and the deposited solution, is dried; and c) subjected to a temperature comprised between 100 and 150°C; and ● to use of this glazing unit in an automotive vehicle, in a building, in interior design, in a mirror, in a household appliance or in a piece of urban furniture, in particular with the aim of decreasing the condensation of moisture on the glazing unit.
